ATENT EDUARD POllL, OF LOUISVILLE, KENTUCKY.

MERRY-GO-ROUND.

SPECIFICATION forming part of Letters Patent No. 476,551, dated June 7,1892.

Application filed October 16, 1891.

To all whom, it may concern.-

Be it known that I, EDUARD POHL, of Louisville, in the county ofJefferson, in the State of Kentucky, have invented new and usefulImprovements in Merry-Go-Rounds, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and eX- actdescription.

This invention relates to that class of devices termed merry-go-roundsor dying dutehmen and it consists in certain improvements in theconstruction and operation thereof, all as hereinafter more particularlypointed out, and specifically referred to in the claim.

In the annexed drawings similar letters and figuresof reference denotecorrespondin gparts in all the views, in which-- Figure l is a plan viewof my in'iprovement, taken as a section on line :0 00, Fig. 2. Fig. 2 isan elevation of my improved device broken 0% at the pedestal or base.Fig. 3 shows the seat on which passengers sit and shows the method ofadjusting the same to suitable elevations for different sizes. Fig. 4 isa detail of the box or hanger in which is held the hearing in which isheld the actuating-shaft which propels the device in a circulardirection. Fig. 5 shows the bottom part of the base orpedestal uponwhich the whole rests when in use.

One of the features to which I wish to call attention is the fact thatmy device as constructed is easily taken apart for shipment and storage,as can be seen from the followin g explanation thereof.

The base or pedestal P rests upon suitable timbers, which serve tosteady the whole while in operation. Rising from the base P are theseveral operative parts of my device, first of which is the bevel-gearO, which is secured rigidly to the base, so as to be immovable.

The base P is slightly reduced in size above the bevel-gear O, and thereis a collar fitted thereon, above which rests a sleeve Q, to which issecured the device A, which consists of a collar provided with severalsockets,into which are fitted the arms A, upon which are secured theseats upon which the passengers are carried while riding upon thedevice. The sleeve Q rises enough above the collar and has length enoughto permit the collars b and c to be se- Serial No. 408,934. (No model.)

cured thereon, and on its top is secured the second bevel-gear D,hereinafter referred to. The arms A may be of any convenient num her andare braced in position by means of the tie-rods F, which are secured tothe collar 0 at one end and to clips c, secured on the arms A, at theother end and are merely hooked in position, so as to be readilydetachable, as occasion may require in shipping.

Lying parallel with and beneath the arms A are provided shafts B, ofsuch a number as may be desired, so that a person sitting on the seats Smay operate the treadles T and by their connection through the chain andsprocket-wheels n m m propel the arms of the device in a circulardirection, this being accomplished through the medium of the bevel-gearC on the inner ends of the rods or shafts B, which mesh with the largergear 0, which is fast to the pedestal P, the latter being always fixedand the gear 0 traveling around the same, said shafts being supported attheir outer ends by a suitable bracket, as like that shown in Fig. 4,and are provided with the sprocket-wheels m on the shafts, while theinner ends of said shafts are supported by similar brackets in abearing-block J, normally held at its lowest position in the bracket bymeans of the compression-spring S, so as to hold the bevel-gear O inmesh with the stationary gear 0, so that rotation of the shafts B willcause corresponding revolution of the bevel-gear C and cause it and itsattachments to be carried in a circle around the central pedestal P. Thesleeve Q, being movable on the central supplemental post P, will causeit to be rotated correspondingly and cause the bevel-gear D on the upperend thereof to turn the pinion D, in mesh therewith, so as to turn thebelt cl and the pulley d and the pulley d on the shaft of thebarrel-organ E, held in the box L, secured at the upper end of saidsupplemental post P. The organ rests inclosed in a box L, from the topof which rises another post P, which may be used to support a canopy-topto protect the riders from the inclemency of the weather.

In Fig. 4 I have shown the hanger in which is held the bearing J, inwhich turns-the shaft B, so as to be movable vertically, so as todisengage the pinion 0 from its engagement with the gear C when desired.The hanger J is constructed so as to form a clip 3 at its upper end toembrace the shaft A, while its lower portion is oblong and holds a blockJ, through which passes the shaft B, the spring S being provided to holdsaid box and its shaft to its lowest position, normally to keep thebevel-gears C and C in engagement, butis capable of vertical elevationto disengage said gears when it is desired to stop the machine by thebrake, the spring S always quickly returning said gears to engagementwhen pressure is released.

At Fig. 3 I have shown a method of seat adjustment which will be foundconvenient in adjusting the elevation of the seat as occasion mayrequire, and it consists of the two lugs 10, which are pinned to the armA by means of the set-screws w and are provided with the seats oropenings 20, through which pass the seat-supporting rods R, secured tothe bottom of the seat S, so that all thatis necessary to raise or lowerthe seat is to loosen the setscrews w" and the rods R will pass freelythrough the openings provided for them in the lugs w. A rod G runs fromthe collar 0 to the back of the seat S, so as to serve as a brace-rod toprevent lateral movement of the seat and its connections on the arm A.This rod G is necessary owing to the strain,which would otherwise beliable to displace the seat during rapid motion of the arms around thebase P, because of the centrifugal force so dc veloped.

In Fig. 2 will be found a brake and lifting device designed to brake themachine and at the same time lift the pinion C out of engagement withthe gear 0 when it is desired to stop the progress of the same. Thisdevice consists of the arm K, pivoted at its lower end to the arm A andat a point near its up per end to the arm K, which runs toward thecenter of the machine, where it joins the cranked arm K, which isprovided at its end with a brake-shoe held nearly, though not quite, incontact with the pedestal P, so that as the arm I is drawn toward therider the shoe Y will bear on the pedestal and stop the progress of themachine. Connected to the arm K is a vertical arm 0, which is providedwith a spoon-shaped end, which lies just beneath the shaft B, so that asthe brake is applied the arm 0 will cause the shaft B to rise and carry*ith it the pinion O on its end, so as to release it from engagementwith the gear 0.

Having described my invention, what I claim is Y In a device of thedescribed class, the standard P, collar A, arms A, shaft B, gears C and0, seat S, the brake-rods K K K, and shoe Y, in combination withsuitable actuating devices for rotating said shaft B, as and for thepurpose specified and shown.

In testimony whereof I have hereunto set my hand this 12th day ofOctober, 1891.
